and Fig. 2 represents a side view of the same applied to the saidthill-coupling.

This `invention appertains to clamps; and consists of `a curvilinearlever, with `one end beveledto a point, in combination with a link orframe, to which it is pivoted, one portion 'of said link beingconstructed with an inclined or bent arm and one portion with a right-anguiar receptacle, asliereinafter shown and described.

The upper curved end of the leverA is beveled to apoint, as seen in Fig. 2, and the lower l curved portion thereof is maderound, so as to furnish a handle, by means of which it may b'econveniently grasped and operated.

B designates a link or frame connected to the lever A, as above setforth, at the end of ing a hollow shoulder or receptacle, the object ofwhich will be apparent from the drawing.

My clamp, in one of its uses, is for holding down one end of the rubberbar or elastic used in connection with thill-couplings of the kind/shownin the drawing, for the purpose of allowing the eyebolt connecting, theshaft to the thill to be readily and easily inserted in its place, asbyl clamping or holding down one end of the said rubber bar, as shown inFig. 2, the said bar will be expanded lengthwise, and consequentlycontracted or made narrow, leaving room for the said bolt while goingthrough the operation above stated, thereby obviatinga difficultyheretofore experienced in g `the introduction of bolts inthill-couplings in Similar letters of reference in the several figuresindicatecorresponding parts of my in-4 which rubber or elastic is used.

The operation of my invention will be read-V ily and fully understood byreference to the iigures of the accompanying drawing.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In testimony that I claim the foregoing as my invention I hereunto setmy hand in presence of two subscribing witnesses.
